Among men, there is not a statistically significant (26) in obesity based on income and very (27) difference based on education, the data show.

The analysis is based on (42) from the National Health and Nutrition Examination Survey, which is considered the gold (43) for evaluating obesity because it is a(an) (44) survey of people whose weight and height are actually (45) rather than being self-reported.
